How NASA's Curiosity rover could 'discover' Teflon on Mars (+video)

NASA's Curiosity rover could contaminate Martian soil, say scientists,
creating misleading evidence of an ancient alien civilization that had
developed nonstick cookware.

An unexpected contamination problem has cropped up for NASA's next Mars rover,
but scientists are confident the huge robot will still be able to
complete its mission after it lands on the Red Planet in August.

NASA scientists discussed the contamination concern and a new Mars landing plan for the car-size Curiosity rover in a teleconference with reporters today (June 11). The contamination issue, they said, concerns the rover's drill.

When Curiosity ultimately bores into a Martian rock, small amounts of Teflon
and other contaminants from the drill will likely seep into the sample,
NASA officials said. These introduced materials may make it tougher for
the Curiosity team to search for organic carbon — the building blocks
of life as we know it here on Earth — on the Red Planet....MORE
